Frank Miller, the contractor and Flip or Flop show regular affectionately referred to as “Frank the Tank” has been popping up a lot on Tarek and Christina El Moussa’s Instagram pages. And for good reason. He is battling stage four cancer, which has become inoperable. In a update on Frank’s condition Tarek wrote, “he’s been fighting multiple cancers for many years, even while filming our show, and he’s still putting up the fight of his life. The doctors told him a year ago he would not make it past 6 months, he’s proving them wrong, this man is a beast.” But the expense of Frank’s surgeries, treatments, and hospital stays has become untenable, and he’s had to use up all his savings. A GoFundMe page was started to help him in his fight, and Christina and Tarek donated $5,000 to get the donating started. They’re also putting the call out to their social media followers to give anything they can – and it seems fans of the HGTV show are stepping up. The campaign has already raise more than $20,000 of its $50,000 goal.
